iopen_go_callback(9)

💫 iopen_go_callback(9) 💫

okay bestie, welcome to the Kernel API Manual — this one's a lil function from the GFS2 filesystem world, and it's literally about queuing up a dcache entry for deletion. no cap. let's get into it 🫶

---

✨ NAME ✨

iopen_go_callback — schedule the dcache entry for the inode to be deleted. that's it, that's the whole job. it's giving cleanup crew energy 🧹✨

---

🌸 SYNOPSIS 🌸

void iopen_go_callback (struct gfs2_glock *gl , bool remote );

yeah she takes two things and returns nothing. void queen, we stan a function that doesn't need to give anything back 💅

---

🎀 ARGUMENTS 🎀

• gl — the glock 💖 (that's the fancy GFS2 lock object, and yes we're just passing her along)
• remote — this one's a bool, and it's true if this came from a different cluster node 🌈 like, someone else in the cluster sent this over, not your local machine, iykyk

---

🦋 DESCRIPTION 🦋

okay so here's the one (1) thing you gotta know: the gl_lockref.lock lock is held while calling this. that's the vibe check for this whole function, fr fr 🔥

lowkey important: that lock is held when this gets called — it's not something you grab yourself, it's already yours when you're in here. don't go acting brand new about it 🙈
